I've been away for the last 2 days, and when I came back, I saw this... My initial thought is to talk to Neo and Pete, and if they don't agree to finish the tournament, I think we can cancel it.
But the tournament should be brought to an end, no matter how many people drop out during the process. As long as there are people who want to win the tournament, we need to give them that opportunity.
In one of the "Bezpredel-2" tournaments, half of my team dropped out during the process, and no one questioned the legitimacy of the winner.
